What is pump.fun?

Introduction

Pump.fun is a service on the Solana blockchain that lets anyone create their own crypto token in under a minute – with no coding skills, no starting capital and no need for anyone to add liquidity. The token can be traded the moment it is created.

That simple idea became one of the most profitable businesses in crypto history. Pump.fun has collected more than $1 billion in fees, over 12 million tokens have been created through it, and it was the main engine of the 2024–2025 memecoin boom. Tokens such as Peanut the Squirrel (PNUT) and Fartcoin were born on the platform and briefly entered the world's top 100 cryptocurrencies.

At the same time pump.fun is one of the most controversial projects in the industry. Fewer than two percent of its tokens have ever progressed from the bonding curve to real trading, the platform and its founders face a class action in the United States, the UK is outside its service area, and Apple removed its app from the US and Indian App Store in September 2026.

This guide covers what pump.fun is, how it works technically, how it makes money, what the PUMP token is and which risks come with using it. If memecoins are new to you, also read our guide to Dogecoin, the original memecoin.

Pump.fun at a glance

History: rapid rise, constant controversy

2024: Explosive growth

Pump.fun launched in January 2024. By May it had become one of the highest fee-earning applications in all of crypto. The same month it suffered its first serious crisis: a former employee abused privileged access to withdrawal authority and used flash loans to take about 12,300 SOL, worth roughly $1.9 million at the time. Trading was halted, contracts were upgraded and users were promised compensation.

In 2024 the platform added livestreaming so creators could promote their coins. The experiment spun out of control as some streamers threatened animals or themselves to pump their token. Pump.fun disabled livestreams in November 2024 and later restored them with stricter moderation.

In December 2024 the UK regulator FCA warned that pump.fun may be providing financial services without authorisation. A few days later the platform permanently blocked UK users.

2025: Peak, own exchange and the PUMP token

January 2025 was the busiest month in the platform's history with about $148 million in fees. The same month the first US class actions were filed against the platform and its founders.

In March 2025 pump.fun launched its own automated exchange, PumpSwap. Until then successful tokens had migrated to the third-party Raydium exchange. In May creator fees were introduced, giving the token creator a share of every trade.

In July 2025 the platform held one of the largest token sales in crypto history. The PUMP public sale sold out in about 12 minutes, raising $600 million at a $4 billion valuation. Around the same time rival LetsBonk briefly became Solana's largest launchpad, but pump.fun won the market back within weeks after starting PUMP buybacks.

September 2025 brought the Project Ascend overhaul, which tied the creator fee to a token's market cap. In October pump.fun acquired the Padre trading terminal, now known as Terminal.

2026: New strategy, new competitors

2026 has been mixed. Fee revenue is well below the 2025 peak: in January 2026 fees were about $32 million, roughly 76% lower than a year earlier. Pump.fun has responded with rapid product changes:

• February: Cashback coins, where the creator fee could be redirected to traders
• April: All bought-back PUMP (about $370 million, ~36% of circulating supply) was burned and replaced with a programmatic model spending 50% of net revenue on buybacks for one year
• May: In-app trading of Ethereum, Base and BNB Chain tokens
• July: Support for Robinhood Chain tokens; team and investor PUMP unlocks began
• September: Custom Pairs, letting tokens pair with assets such as tokenised stocks, and Holder Rewards, which replaced Cashback

Competition has been fierce. Robinhood Chain launchpads and Solana's StonkFun briefly overtook pump.fun in daily revenue in August and September 2026, but by the end of September pump.fun was again the largest in its category.

How does pump.fun work?

At its core pump.fun is a simple set of smart contracts that automates a token's whole life cycle from creation to trading, with no capital or market maker required from the creator.

Creating a token

The user gives the token a name, ticker, image and optionally a description and social links. There's no creation fee – just the Solana network fee and a small deposit the network requires to open the token's accounts. Every token has a total supply of one billion. Nothing is pre-allocated to a team or investors and there are no presales; even the creator buys on the same curve as everyone else. The platform calls this a "fair launch".

The bonding curve

A new token isn't traded on an exchange at first but directly against a smart contract, with the price set by a mathematical formula called a bonding curve:

• Every buy raises the price and every sell lowers it
• The smart contract is always the counterparty, so buying and selling work instantly
• The earliest buyers get the lowest price, and the price climbs steeply as demand grows

The curve acts as an automated market maker, giving a token a price and liquidity without anyone depositing funds into a pool – the same principle behind decentralised exchanges (DEXs).

Graduation and PumpSwap

Once about 85 SOL of buys have accumulated on the curve, the token "graduates". Historically that has corresponded to a market cap of roughly $60,000–100,000 depending on SOL's price. The SOL and remaining tokens are then automatically moved into a liquidity pool on PumpSwap, and the pool's LP tokens are burned so no one – not even the creator – can pull the liquidity. This prevents the classic "rug pull" of draining the pool. Migration costs 0.015 SOL, deducted from the curve's funds; tokens that graduated before March 2025 went to Raydium.

Graduation is rare. According to The Block's on-chain data, fewer than 2% of all pump.fun tokens have ever graduated. Most die on the curve within hours or days.

Fee structure

Pump.fun earns from trading fees. According to its fee page (updated 8.10.2026):

Put that in perspective: a round trip on the bonding curve costs about 2.5% in fees, plus Solana network fees and any third-party trading-bot fees.

Creator fees, Holder Rewards and Cashback

• Creator Fee: The default model, paying the creator a share of every trade. Project Ascend (September 2025) tied the share to market cap – smaller tokens pay the creator a higher percentage.
• Community Takeover (CTO): If a creator abandons a token, a community-chosen team can apply to receive the creator fees.
• Cashback (Feb–Sep 2026): The creator could redirect fees to traders. Removed for new tokens; old Cashback coins still work.
• Holder Rewards (since Sep 2026): The creator fee is distributed automatically to holders pro rata, for holdings worth at least $20. The choice is made at launch and is irreversible.

Holder Rewards are not dividends or a guaranteed return. Under the terms, distributions can be paused or reversed and they don't compensate for a falling token price.

Custom Pairs

Launched in September 2026, Custom Pairs lets a token pair with assets other than SOL and USDC – tokenised stocks (e.g. Nvidia and Tesla), a tokenised S&P 500 fund, wrapped bitcoin, metals or PUMP. There were 93 pairs at launch. The creator fee is paid in the pair asset, and half of the protocol revenue from Custom Pairs goes to PUMP buybacks. Important: a memecoin paired with a stock gives no rights whatsoever to the stock, and tokenised stocks sit in a regulatory grey area.

Terminal, mobile app and cross-chain trading

• Terminal: The Padre terminal acquired in October 2025, a multi-chain tool for advanced traders.
• Mobile app: iOS and Android, with wallets created via email or Google through Privy.
• Cross-chain trading: Trade Ethereum, Base, BNB Chain and Robinhood Chain tokens using SOL, with no separate bridge.
• Mayhem mode: Introduced in late 2025 – an AI agent trades a new token during its first 24 hours.
• Limit orders: Take profit and stop loss.

The PUMP token

PUMP was sold in an ICO starting 12.7.2025 at $0.004, a $4 billion fully diluted valuation. The sale was meant to run for 72 hours but the public portion sold out in about 12 minutes. US and UK residents were excluded.

Team and investor allocations had a one-year lock that ended on 12.7.2026, when the first 82.5 billion PUMP unlocked; the rest vests linearly over about three years, adding steady supply.

Buybacks and burns

• July 2025 – April 2026: Practically all revenue went to buybacks, but the tokens initially sat in the treasury, raising questions.
• 28.4.2026: All bought-back tokens were burned and a programmatic buy-and-burn model began, directing 50% of net revenue from the curve, PumpSwap and Terminal to buybacks until April 2027.
• October 2026: Per the platform's tracker, about $476 million had been spent and over 170 billion tokens (~17% of supply) burned.

What PUMP is not

PUMP holders have no right to revenue, dividends or other distributions, and there is currently no formal governance. Buybacks and fees are decided by the team. Buybacks haven't prevented price falls either: PUMP traded below its ICO price for long periods, bottomed around $0.0013 in June 2026 and was about $0.0055 in early October 2026. According to Arkham Intelligence, pump.fun-linked addresses held around $2.8 billion in early October 2026, mostly in PUMP, and the platform has sold hundreds of millions of dollars' worth of SOL.

The business in numbers

The platform earns on every trade whether the token rises or falls. An autumn 2026 analysis by Talos of about 150 memecoins that reached centralised exchanges – relatively successful tokens – found 81% had fallen at least 90% from their peak, and only five of 151 traded above their first-day price. That is pump.fun's core contradiction: the platform profits from trading velocity, while each holder depends on buyers returning to their particular token.

Pump.fun vs other launchpads

• LetsBonk (bonk.fun): Backed by the BONK community and routes fees to BONK buybacks. Briefly Solana's largest launchpad in July 2025 before pump.fun's buybacks took the lead back.
• StonkFun: Launched August 2026, first to bring stock-paired memecoins to Solana at scale; pump.fun answered with Custom Pairs.
• Pons (Robinhood Chain): Leading Robinhood Chain launchpad, trading tokens against tokenised stocks. Robinhood Chain launchpads briefly cut pump.fun's share of category fees to ~27% in July 2026. See our guide What is Robinhood.
• Raydium LaunchLab: Launchpad of the veteran Solana DEX that once hosted pump.fun's graduated tokens; also provides infrastructure to others.
• Four.meme (BNB Chain): The most popular equivalent on BNB Chain.

Strengths: ✅ largest user base, brand and liquidity in Solana memecoins ✅ free, instant token creation ✅ liquidity permanently locked at graduation ✅ own exchange, terminal and app ✅ fast product development.

Legal and regulatory issues

US class action

Operator Baton Corporation and its three founders are defendants in a class action in the US District Court for the Southern District of New York (Aguilar v. Baton Corporation), filed in January 2025 over unregistered securities and later expanded with RICO claims. Plaintiffs describe the platform as a "digital casino". On 31.8.2026 Judge Colleen McMahon dismissed the securities claims and all claims against Solana Labs, the Solana Foundation and their executives, but allowed the RICO claims against Baton Corporation and its founders to proceed. These are unproven allegations and the case is ongoing.

UK, Apple and terms of service

UK users have been blocked since December 2024. On 10.9.2026 – the day after Custom Pairs launched – the iOS app disappeared from the US and Indian App Store; pump.fun calls it temporary and Apple hasn't commented. The terms require users to be 18+, send disputes to binding arbitration in the British Virgin Islands with a class-action waiver, and generally cap liability at fees paid or $100 – though mandatory EU consumer rights can't be excluded.

Regulation and tax

Pump.fun is not a licensed exchange and offers no regulated investor protection. In the EU, crypto service providers need a MiCA licence – check the ESMA register before using any service. In most countries, swapping one crypto for another is a taxable event, so every memecoin bought with SOL and sold back is taxable, and active trading quickly produces hundreds of records. Creator fees and Holder Rewards are likely taxable income when received. See our crypto tax basics guide and check your local tax authority's guidance.

Practical guide: using pump.fun and buying PUMP

This section is not investment advice. Memecoin trading is essentially speculation where most participants lose money.

What you need

• A Solana wallet: e.g. Phantom, Solflare or Backpack. The pump.fun app can create a wallet via email or Google, but then custody relies on a third party (Privy). See how to create a crypto wallet.
• SOL: For trades and network fees, bought on a regulated exchange such as Coinbase or Binance and withdrawn to your wallet.

How trading works

1. Connect your wallet to the pump.fun website or log in to the app
2. Choose a token and check its details carefully
3. Enter the amount in SOL and set slippage
4. Approve the trade in your wallet
5. Selling works the same way; after graduation trades route automatically to PumpSwap

Red flags when assessing a token

Because creating tokens is free, the platform is full of junk and scams. Risk-monitoring firm Solidus Labs analysed over seven million pump.fun tokens (January 2024 – March 2025) and found 98.6% collapsed in pump-and-dump patterns soon after launch; only about 97,000 kept more than $1,000 of liquidity. Check at least:

• Creator holdings: Do the creator or a few wallets hold a large share?
• Bundling: Did linked wallets buy much of the supply right after creation?
• Sniper bots: Bots buy within seconds and sell to later buyers – humans are practically always late.
• Holder distribution: How concentrated are the top ten holders?
• Community and socials: Are the links real or is activity artificial?
• Over-promising: "Guaranteed 100x" is always a red flag.

Graduation guarantees nothing: locked liquidity stops the pool being drained, not large holders dumping.

Buying the PUMP token

PUMP is listed on several large international exchanges, such as Bybit and Binance, and on Solana DEXs. Availability varies by country – choose an exchange licensed in your jurisdiction. New to investing? Start with our crypto investing basics.

⚠️ Key risks

• Loss of value: Fewer than 2% of tokens graduate, and most graduates lose most of their value.
• Unfair playing field: Bots, insider wallets and bundled buys are almost always ahead of ordinary users.
• Fees: ~2.5% round-trip fees on the curve erode returns fast.
• Legal risk: The ongoing RICO case could affect operations.
• Regulatory risk: Already closed to UK users; tokenised stocks raise new questions.
• PUMP risks: No revenue rights, ongoing unlocks, buybacks committed only until April 2027, centralised fee decisions.
• Competition: Market share has swung quickly.
• Solana dependency: Congestion, outages and SOL's price affect the platform directly.
• Security: The platform has already lost funds to an insider attack once.

Conclusion

Pump.fun is one of crypto's defining phenomena. It made launching a token as easy as posting on social media and built a business that earned over $1 billion in under three years. Technically it's clever: the bonding curve gives tokens liquidity without capital, and permanently locking liquidity removes one of the oldest scams.

Yet it's also a textbook case of a platform and its users living in different economic realities. The platform earns on every trade, while most tokens lose their value and early bots and insiders capture much of the profit. Use it as a window into how on-chain markets and AMMs work – but treat memecoin trading as closer to gambling than investing, using only money you can afford to lose entirely. PUMP itself is a bet on the platform's future, without any legal claim on its revenue – a crucial difference from a stock.

As with all crypto investing, do your own research, understand the risks and never invest more than you can afford to lose.
